Abstract

In a previous paper [ Tackley , 2000b] it was shown that a combination of temperature‐dependent viscosity and viscoplastic yielding is sufficient to give rudimentary plate tectonic‐like behavior in three‐dimensional models of mantle convection. Here the calculations are extended to include two complexities that have been suggested as being important in localizing deformation at plate boundaries: strain weakening and the presence of a low‐viscosity asthenosphere. Introducing an asthenosphere by reducing the viscosity by a factor of 10 where material reaches a solidus (1) dramatically improves plate quality, even if the asthenosphere is restricted to regions around spreading centers, (2) gives good, smoothly evolving platelike behavior over a wide range of yield stress values spanning an order of magnitude, and (3) gives bimodal stable solutions over a range of yield stresses; either immobile‐lid or plate behavior may be obtained, depending on initial condition. By contrast, introducing an asthenosphere by using depth‐dependent viscosity has a much smaller effect on system behavior. Increasing strain weakening (1) improves localization at spreading centers but leads to an increasingly complex network of spreading centers fragmenting the plates, (2) weakens convergent zones and can make downwellings highly episodic, and (3) does not lead to pure transform boundaries in these calculations. Time‐dependent “damage” evolution and instantaneous strain‐rate weakening give very similar…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
